Definitions

  • Examples of devices that enable creation of videos include video cameras and handheld devices with an integrated camera.
  • a variety of web-based services exist that enable individuals to share videos via the Internet.
  • a web site may enable individuals to upload videos so that the videos may be viewed by friends and family-
  • a web site that enables individuals to share videos may benefit by offering a video printing service that enables clients to browse videos and select individual video frames for printing.
  • Providing a web-based video browsing may present a number of problems.
  • web clients may connect to a web server using a variety of different network connections that- yield different communication speeds.
  • a video browsing and selection system that is adapted to a high speed connection may not work well using a low speed connections, and visa versa.
  • the source videos from which video frames are selected may include a large number of video frames and browsing large numbers of video frames may impose an undesirable burden on a user.
  • a system for web-based video browsing including a web server and a web client that cooperatively provide a set of video browsing functions.
  • the video browsing functions enable a user of the web client to browse a source video and select a video frame from the source video without imposing an excessive burden on the user.
  • the distribution- of the video browsing functions between the web server and the web client may be adapted to a communication speed between the web server and the web client.
  • Figure 1 shows a web-based video browsing system according to the present teachings
  • Figures 2-6 show example distributions of a set of video browsing functions among a web client and a web server
  • Figures 7a-7d illustrate a semi-automatic method for selecting a video frame.
  • FIG. 1 shows a web-based video browsing system 100 according to the present teachings.
